there are no ways currently to downgrade psp's from 6.00 to 5.00m33 also if you have a PSP 3000 or a later 2000 model it will only brick it if you try.

Pandora's Ultimate Magic Stick 3.80M33-5


New version of UPMSv3 - universal PSP Unbricker/Downgrader/Upgrader, also known as Pandora's Ultimate Magic Stick, Now work with DC ver4 (Dark_AleX’s), for installing CFw 3.80M33-5 and creating memory stick into a “Ultimate Magic Stick” for use with “Pandora’s battery” (jigkick). Works for both PSP, Slim and/or Fat, and 1 stick for all functions for Unbricker/Downgrader tools. Also available is the “UPMS_v3.pdf Guide” to help you get started and usage.

The Ultimate Pandora’s Magic Stick is the simple solution to easily accomplish any of the following:
  • Recover any bricked PSP (Fat or Slim) and install sony firmware or CFw M33.
  • Upgrade Fat-Slims PSP to CFw 3.80M33-5, with 1.50 kernel patch-Fat Only.
  • Upgrade Fat-Slims PSP to CFw 3.71 M33-2, with 1.50 kernel patch-2 -Fat Only.
  • Update to 3.71M33-4 are installed to the ‘GAME’ folder from the XMB.
  • Downgrade Fat PSP to Fw 1.50.
  • Upgrade Fat PSP straight to CFw 3.52M33 from Extended Boot Menu then install update 3.52 M33-4 from XMB, without need to downgrade to 1.50.
  • Boot up PSP using Ultimate Loader with support for choosing which Pandora’s you reach V1, V3 or V4.
  • Boot up PSP to XMB with UPMS inserted-Fat Only.
  • Boot up to a full FW 1.50 from Memory Stick-Fat Only.
  • Use PSP Filer and other tools (If it requires 1.50, can’t for Slims).
Note: This software is free, and comes with no warranty. Despite it has been tested and it has worked, there is some risk with any PSP operation that involves flashing, so please try this at your own risk!.

Only Memory Stick "Pro Duo" are compatible. Memory Stick Duo are not supported. Read more... for installation

Downgrading my psp 5.51 to 3.70 m33


Sorry Ryan, you will need a service or pandora battery to reload custom firmware.

This will let you back up games you already own and run them from the memory stick.

You can create a pandora battery and the 'magic' memory stick from any psp already running custom firmware. You can also buy them online, and if you look in the local classified ads website where you live, you can probably find people offering that downgrading service.

I cannot run through the steps here to create your own, but tutorials are all over the net and sites like youtube.

Use a pandora battery to flash anny firmware you like.

You have updated your custom firmware with the original firmware from Sony.

You'll have to downgrade your firmware to update to the newest custom firmware using the pandora battery or update using the pandora battery to update directly to the newest custom firmware build.

Succes.

Downgrade psp 5.01 to 5.00 m33


If you are on psp 3000 series then you will have to live with it and buy UMDs for the time being.If not you can get a pandora battery and downgrade it to whatever you want.Since you are on 5.01 OFW I highly doubt your mobo is still trigger-able by pandora battery though.
